tion of said bla 5 5 'a plan view of the same, also with effective and convenient manner at the minimum expense and labor. I

Said. lnvention' therefore consists of the structural features substantially as hereinafter fully disclosed and specifically pointed out by the claims. w

In the accompanying drawing illustrating the preferred embodiment of my invention- Figure l is a broken sectional elevation thereof. Fig. 3 is certain parts shown partially broken away.. Fig. 4 is an inverted view, with broken off. Fig. 5 is'a detac ed view of the Fig. 6 is a full view taken from the underside so far as relates to the cutting apparatus. Fig. 7 is an enlargeddetailed view showing more fully the pivotal connection 4* betweenthe rod 4 and the blade 3. v

' In carrying out my invention, I suitably fix orrigidly secure to the lower end of a handle-bar 1, and upon its underside so that it shall have about the inclination indicated,.a

blade or cu'tter 2, preferably terminated at its inner end in a lateral plate-like extension or enlargement 2*, with its inner or tang por tion bent or conformed to the preferably curved or rounded surface or said .end of said handle-bar. A second or companion blade or cutter 3 is arranged or ada blade or cutter after the fashion of the blades of ordinary shears, it having fixed thereto,

upon its upper surface, at the heel-end, a p ate-like piece or member- 3 practically forming an inte ral ,portion of said blade or cutter and whic is pivoted at one-of its forward corner-edges, asat 3*, to the lateral plate-like extension 2*- of the fixed or stationary blade, about midway of that edge of said extension thus dproviding'for the pivotal ace as presently see The heel-plate or member 3 of the pivoted side elevation, and Fig. 2 is a' arts partially heel-portion of pted to co-operate with the aforesaidm the mowing or cutting operation.

An additional rbd or lever 6 is connected to at 4 ajpit- I upper the aforesaid lever and adapted to be manually actuated while the pushed from said handle-bar, as in'perform- It will be noted that actuating the aforesaidparts they have a cam or eccentric action and that the pivoted or movable blade or cutt r is caused to co-operate with the stationary blade 2 and thus provide for ashear-action between said or mowing operation. The pivoting screwbolts 3 and 4 tively, are connecte together by-an in exible link 7 for steady and positive action between the blades and forstability and the bracing of the parts noted. I

A shoe 8, 1n the form of aplate or shield, suitably bolted or secured preferably to the stationary blade or cutter 2, upon its underside, and to the rear-side of the handle-bar 1, is offset from the lower tions of the Blades and their adj unctive parts, or removing the same from contact with the ground surface, the purpose of which is obvious. vious that in lieu of mounting said, parts u on the shoe, wheels may be provided for t at pu ose.

In or er to reduce effective or cutting edges of the blades into a shearing relation, arotary disk, roll or wheel -9 is suitably. journaledor pivoted upon .the handle-bar 1, near its lower end, so as to enor cutter 2 is suitablybraced in position, to-

Also, it is obtween the shoe or shield 8 at its forward end, and the underside of said blade; It is further noted that both the pull exerted upon the blade actuating lever and the pushing 7 action delivered through the handle-member, assist the blades in performing the cutting operation.

I claim: I

1. A device of the character described, comprising a handle-equipped member having a fixed blade at its lower end provided with a lateral heel-extension, a second blade having also extensions projecting therefrom,

said second blade being pivotally connected comprising a handle-member having a fixed blade at its lower end, a movable blade cooperating with the aforesaid blade, each of said blades having an extension projecting from the same side as the extension from the other blade and pivotally connected -together, said movable blade also having an extension projecting from itsopposite side, a rod or pitman cdnnected to said last named extension at one side of the line of the cutting action of said blades, a link connected to the means forming connection between 1 said blades'and between one of said blades and said rod or pitman, and means connected to said rod or pitman for its convenient actuation.

3. A lawn mower, comprising a handlemember rovided with a fixed blade equipped with a ateral heel-extension, a movable blade also having a corresponding extension pivoted to the aforesaid extension at one side of the line of the cutting action of said blades, and means for actuating said movable blade, embracing a pitman or rod connected to the heel-end of said movable blade at the opposite side, said handle-member being equipped with a rotary disk or roll adapted to engage theheel-end of said movable blade, and said movable blade actuating means also including a lever fulcrumed upon said handlemember and having connected thereto said pitman, and a hand-lever connected to the aforesaid lever.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses. i
